  • Sec. 4.  Using National Security Assets for Law and Order.  (a)  Within 90 days of the date of this order, the Attorney General and the Secretary of Defense, in consultation with the Secretary of Homeland Security and the heads of agencies as appropriate, shall increase the provision of excess military and national security assets in local jurisdictions to assist State and local law enforcement.
    (b)  Within 90 days of the date of this order, the Secretary of Defense, in coordination with the Attorney General, shall determine how military and national security assets, training, non-lethal capabilities, and personnel can most effectively be utilized to prevent crime.

    Following ones will surely be lethal capabilities. We’re cooked.













  • A typical data center rack holds about 40 servers, each with at least two networking interfaces. According to Boote, the Ethernet interfaces of a single rack draw 160 watts in total.

    “Reducing the power draw of a data center, which may have hundreds or thousands of racks, would be akin to an energy savings of switching a building from incandescent to more energy efficient LED lighting and be well worth the investment,” he told LinuxInsider.

    According to Boote, this optimization fixes a part of the kernel written when lower-speed Ethernet interfaces drew a fraction of today’s electrical needs. The networking stack design did not account for the growing power budget required by modern networking interfaces.

    “By changing the priority of how the computers schedule tasks during high bandwidth events, a computer can better deal with networking traffic and prioritize energy expenditure in a way that makes sense for modern hardware and architectures,” he reasoned.

    Oh boy, where do I even start? This comment is wrong in multiple ways. Let’s break it down:

    1. “The way triangulation works is by essentially measuring distance.”

      • Nope. This describes trilateration, not triangulation.
      • Triangulation uses angles, while trilateration uses distances. GPS works via trilateration.
    2. “1 satellite distance puts you anywhere in a radius (circle) of that satellite.”

      • Kind of, but missing a crucial detail:
        • A single satellite defines a sphere around itself (not just a circle—you exist in 3D space).
    3. “2 Satellites puts you at 1 of 2 locations where those radiuses intersect.”

      • Wrong. Two satellite distance spheres intersect to form a circle, not just two points.
    4. “3 satellites gives you a single location.”

      • Mostly right, but incomplete.
      • In theory, three satellites narrow it down to two possible points, but one is often out in space or somewhere unrealistic, so it can often be ruled out.
      • However, because your device lacks an atomic clock, it typically requires four satellites to synchronize time properly.
    5. “That’s why it’s called triangulation. Tri = 3”

      • Nope. GPS does NOT use triangulation.
      • The “tri” in triangulation comes from angles, not the number of satellites. GPS uses trilateration, which is based on measuring distances, not angles.

    Final Verdict

    This comment is a trainwreck of incorrect terms and flawed explanations. If they meant “trilateration,” at least part of it would make sense, but calling it “triangulation” completely ruins their credibility.

    So, in short? No, their comment is very incorrect. 🚨
